I have purchased a boost gauge glo shift, i took it to the shop to get it installed, but they told me the t is to big, i was wondering if any one knows what is the actual size for the t tube on a stock au turbo, thank you all in advance.

 

you can find out for yourself. locate the tube near the front left of your intake.. its a black rubber tube about a 1/2 inch thick. this tube runs to your diverter valve. go to the auto parts store and buy one of those multiple size vacuum line T fittings (you can just cut it to size with dikes i.e. 'alternative lifestyle pliers'). or... make a guess and buy the right size.. auto parts stores are usually cool about you taking stuff out to your car to see if its the right part- make sure you ask first to avoid getting tackled. look up the DIY threads for installing boost guages and you will likely find a picture of the hose.. acutally **** it ill do it for you.. as you can see in the picture, it shows a T fitting already installed, this is how yours will look when it is hooked up!

8. Now you have two options for tapping into the manifold pressure to get the reading. One is the Fuel Pressure regulator, the other is the hose that runs to the N249 located at the very front of the intake manifold. This is the method I went with. On my other car I tapped into the FPR with out any problems, so either way is fine.


remember.. as Bob Barker always said "Help control the pet population. Have your pet spayed or neutered. So COME ON DOWN!"
